METHOD FOR PREPARING CLONOGENIC FIBROBLASTS, METHOD FOR GENE TRANSFECTION OF FIBROBLASTS AND GENE-TRANSFECTED FIBROBLASTS SO OBTAINED

摘要

The invention relates to a process for preparing clonogenic fibroblasts, with tissue being removed from the donor and the individual cells being isolated from the tissue, the resulting cell suspension being strained, the cells which are contained in the cell suspension being washed and the cells being converted into a tissue culture, with the exception of the isolation of individual cells by mechanical comminution, followed by an enzymic treatment with collagenase alone, and with at least one gene being inserted into the fibroblasts by means of the transfection, which gene encodes a biologically active protein, preferably a therapeutically active protein, for example a growth factor, a hormone, an enzyme, a coagulation factor or a coagulation inhibitor.
